Corporate preferences and adoption behavior towards bidirectional charging

Bidirectional charging is regarded as a key enabler for integrating renewable energies and stabilizing electricity grids. While existing research on the acceptance of bidirectional charging has predominantly focused on private users, the perspective of companies, where vehicles are typically parked throughout the day and who operate fleets, is underexplored. To address this gap, this study provides a quantitative analysis of corporate acceptance of bidirectional charging, using a choice-based conjoint analysis with 174 German companies. The results reveal that firms largely value self-optimization and contributions to sustainability goals but are reluctant to take on lengthy amortization timelines and high vehicle value loss. A cluster analysis further identifies three distinct adoption segments. These findings highlight both opportunities and barriers for market diffusion and provide actionable implications for policymakers and practitioners aiming to accelerate the adoption of bidirectional charging in the corporate sector.
